Syntax
DBSWIT(type,input,low,high,pt1,...,pt12)
type | The type of dead band switch action. - Valid values are 0 and 1. 0 = All output points (pt1,...,pt12) are commanded ON when the input point value rises above the high limit, and are commanded OFF when the input point value falls below the low limit. 1 = All output points (pt1,...,pt12) are commanded ON when the input point value falls below the low limit, and are commanded OFF when the input point value rises above the high limit. |
Input | Point name of the variable being controlled. - This parameter is usually an analog point, but it can also be a local variable. |
low | The low temperature at which a switching action occurs. - This parameter can be an integer, point name, local variable name, or decimal number. |
high | The high temperature at which a switching action occurs. - This parameter can be an integer, point name, local variable name, or decimal number. |
pt1 through pt12 | Name of an output point to be turned ON and OFF. - Local variables can be used. |
Use
Provides the ON/OFF switching action of an output point. This is the software equivalent of a thermostat.
- A maximum of 12 points can be controlled with one DBSWIT command.
- The operational status of the point is regulated by an analog point using a predefined dead band.

Notes
The ACT and ENABLE commands can be used interchangeably.
